If you use the social scheduling tool Buffer than chances are your Saturday morning was a bit of a nightmare.

Thousands of accounts were hacked this morning through Buffer, and spammers sent out 10s of thousands of weight loss spam messages on Facebook and Twitter through Buffer.

“Hi all. So sorry, it looks like we’ve been compromised,” the terse statement reads. “Temporarily pausing all posts as we investigate. We’ll update ASAP.”

Buffer has recently put an update on their blog that goes on to say that the site was hacked and individual social media account passwords were not compromised, just the Buffer tool itself as a means to send out the unauthorized tweets and facebook spam.
